Red spots on the skin stem from various causes. Dermatitis may result from irritating substances, ringworms from fungal infections, purpura from burst blood vessels, and autoimmune conditions that can trigger rashes. While some spots resolve on their own, others require treatment. Explore 13 potential causes of red spots, learn if they warrant concern, and discover when immediate medical attention is necessary.
On the other hand, skin spots appear differently across various tones. Acne may appear red on lighter skin and dark spots on darker tones.
1. Heat Rash (Miliaria)
Sun-induced red spots, known as “heat rash” or miliaria, result from blocked sweat glands under the skin, leading to small, itchy, or painful red bumps. Typically found in skin folds and sweat-prone areas like the armpits, chest, back, arms, and groin..
Living in hot climates, excessive sweating, or prolonged bed rest increases the risk of heat rash. Treat it by cooling the skin with baths, cold compresses, and loose clothing. Avoid thick moisturizers that trap heat.
Heat rash typically improves within days, but if the skin is injured, it may lead to infection. Severe cases may require oral or topical antibiotics to alleviate pain and clear the infection.
Contact your healthcare provider if you observe signs of infection, such as a whitish color over the heat rash, flaking skin, or pus-like discharge.
2. Cherry Angiomas
